The Dallas Cowboys are hitting the reset button on defense - and they’re not doing it halfway. After a 2025 season that saw the unit give up more points than any other in franchise history, Dallas is overhauling the defensive side of the ball, starting with a fresh face at the top and continuing with a key hire in the middle.
It all begins with 34-year-old Christian Parker, who takes over as defensive coordinator. Parker comes in from Philadelphia, where he served as the Eagles’ defensive passing-game coordinator.
He replaces Matt Eberflus and brings with him a philosophy built on disguise, deception, and calculated aggression. The Cowboys are clearly leaning into a younger, more energetic coaching identity - one that’s designed to confuse offenses rather than simply react to them.
And now they’ve added another crucial piece to that puzzle: Scott Symons, the new inside linebackers coach. Symons arrives from SMU, where he spent the last four seasons as the defensive coordinator and safeties coach.
He’s not just a local hire - though returning to his Dallas roots certainly doesn’t hurt - he’s one of the most respected defensive minds in the college game. Several NFL teams were in the mix for his services, but the Cowboys landed him, giving Parker a trusted lieutenant to help reshape the heart of the defense.
So what exactly are the Cowboys getting in Symons? Let’s break it down.
1. A Coach Who Creates Chaos
Symons’ defenses don’t just show up - they show out. At SMU, his units were known for generating havoc, whether it was through sacks, forced fumbles, or interceptions.
In 2025, the Mustangs finished fifth nationally in total takeaways. That kind of production doesn’t happen by accident - it’s the result of an aggressive mindset and a scheme that puts players in position to make plays.
2. A Run Defense That Stands Its Ground
Stopping the run is still the foundation of any great defense, and Symons’ track record here is rock solid. In 2024, SMU allowed just 100.2 rushing yards per game, ranking seventh in the nation.
That’s not just stout - that’s stonewalling. His defenses consistently won at the line of scrimmage, turning opposing ground games into non-factors.
3. Clutch in the Red Zone
Symons’ defenses didn’t just look good between the 20s - they tightened up when it mattered most. His units were among the best in the country at red zone defense, finishing second in the FBS in 2024 and fifth in 2025. That kind of situational excellence is exactly what the Cowboys need after a season where they struggled to get stops when it counted.
4. A Proven Winner
Symons helped guide SMU to its first-ever College Football Playoff appearance in 2024 - a milestone moment for the program. That kind of success speaks to his ability to build and lead a defense that can compete at the highest level. He’s not just a scheme guy; he’s a culture guy, too.
5. Master of Disguise
One of Symons’ calling cards is his ability to teach complex, multiple-front defenses in a way that players can execute cleanly - and quarterbacks can’t read easily. He’s known for disguising coverages and mixing five-man pressure looks that keep offenses guessing. That aligns perfectly with Parker’s vision for a defense built on confusion and unpredictability.
6. Fundamentals First
Symons brings an old-school intensity with a modern twist. His practices are fast-paced and focused on discipline - sprinting on and off the field, relentless effort, and physical play.
He demands mental sharpness and physical toughness, and he gets it. That kind of attention to detail will be critical in reshaping the Cowboys’ linebacker corps.
Now, the challenge is translating all of that from the college game to the NFL - no small feat. But if Symons can bring even a portion of that havoc-wreaking, red-zone-clamping, run-stuffing energy to the Cowboys’ second level, this defense could finally start turning the tide.
Last season, the Cowboys’ D was generous - too generous. They gave up yards, gave up points, and gave up control.
With Symons joining Parker on the sideline, the goal is clear: flip the script. Take the fight to offenses.
Be the aggressor. And above all, stop giving - and start taking.
